Usage Guidelines

Usage Scenario

In BGP/MPLS IP VPN networking, after running the ip vpn-instance command to create a VPN instance, you can run the ipv4-family command to enable the IPv4 address family for the VPN instance and perform VPN configurations in the address family view if you want to have IPv4 VPN routes advertised and IPv4 VPN data forwarded.

Follow-up Procedure

Run the route-distinguisher command to configure an RD for the IPv4 address family of the VPN instance. VPN configurations can be performed in the IPv4 address family view only after an RD is configured for the IPv4 address family of the VPN instance.

Precautions

Configurations of the commands run in the VPN instance view, except the description command, are automatically synchronized to the VPN instance IPv4 address family view.

Example

# Enable the IPv4 address family for a VPN instance.

<HUAWEI> system-view
[~HUAWEI] ip vpn-instance vrf1
[*HUAWEI-vpn-instance-vrf1] ipv4-family
[*HUAWEI-vpn-instance-vrf1-af-ipv4]
